In 4.0.3a, both of these elements were nerfed excessively. Protector of the Innocent only heals you now when you heal someone else (which means it is absolutely useless if you're alone). Second, Blessed Life can only proc once every 8 seconds now. So now you have a shortage of Holy Power in PvP and also a shortage of self-heals.
Let's say you're healing one other person. If you Beacon of Light on them, you gain Holy Power through Tower of Radiance (Healing the target of your Beacon of Light with Flash of Light, Holy Light, or Divine Light has a 100% chance to generate a charge of Holy Power). This too is useless for PvP. You're already healing them, so the Beacon of Light does nothing. However, if you put Beacon of Light on yourself, then you don't gain Holy Power through FoL, HL, or DL when you heal your target, only when you heal yourself (and we come full circle, because if you're healing yourself with beacon of light on you, then Protector of the Innocent doesn't proc).
Once you get stunned or silenced, there's absolutely no way to recover from the damage unless Divine Shield is up. Before 4.0.3a, you could at least use Word of Glory, because sitting through the silence/stun, you'd rack up 3 charges of Holy Power, and you'd recover with Word of Glory + Protector of the Innocent. Now you have Holy Shock -> Word of Glory (2 charges -- one from getting hit, one from holy shock). Although Holy Power gains lag pretty hard, so doing Holy Shock -> Word of Glory will probably actually cast Word of Glory as if you only had 1 Holy Power up.
Anything with a cast time is pretty worthless if you're being focused. The amount of stuns, silences, lockouts, interrupts, and pushback is far too much. Paladins have very, very little absorption (through useless mastery -- a whole 10% of my healing done) and no HoTs (save for Long Word glyph, which is also useless).
I'd have more self healing and holy power as Retribution than I do currently as Holy. Sad, sad state.
